6．Bali is，without doubt，one of the most culturally rich islands in the world．In fact，its carved temples，dances and rice terrace all seem too perfect to be true，even down to the people's smiled．But take a closer look at those smiles and the perfect seem a bit too perfect，and for good reason．Those flattened teeth are the result of an important piece of dentistry that every young Balinese man or woman experiences in their life，known as not performed for tooth filing（锉）
Tooth filing is part of Bali's religious tradition and is not performed for cosmetic（美容的） reasons．In fact，so important is the tooth filing ceremony that without it，the Balinese believe they may experience serous social or behavioral problems later in life，or their personality may change altogether．It is held to purify the body and mind，which is central to Balinese religious life．According to the Balinese，at every stage in a person's life，he or she is likely to be influenced by the supernatural-from demons and layak，to good spirits which may bring good luck．
The Balinese believe that long pointed teeth give the person the animal sides of human nature，such as desire，anger and greed．And those animal sides are more likely to show up when the teeth are sharp．To prevent this，the pints of the teeth are filed down，together with the points of the lower teeth in a potong gigi ceremony．However，people who have their teeth filed will suffer early tooth decay（蛀牙）since the protection is removed from the points of the teeth，exposing them to acid decay．
The potong gigi ceremony is usually performed for the members of the same family together since it is a very expensive occasion to host．It is often necessary to wait until the youngest child is of age．A special chair is to be made for the ceremony from bamboo covered with coconut leaves，blankets and flowers．Surrounding the platform is food the coning guests．
